Miss Belindel handed Shard some information on the "Ritual: Summoning the Shadow of [Seven-Tail Performer]." Although it's incomplete, the essential parts are there, most importantly the ceremony contents and the prayer. To initiate the ritual requires sacrificing a large amount of fresh flesh and bone remains, and if the quantity is insufficient, the flesh of beings like dragons can be used as a higher-quality substitute.
As for the prayer, it is recorded on a parchment roll handwritten by the witch. When Shard unrolled it in the study at home, Miss Galina, who was also interested, looked over and frowned at the writing:
"If Bella wasn't dizzy when she copied it, then these terrifying symbols shaped like musical notes are truly strange. I have never seen such a script, but just by looking at it, I can hear sounds in my ears."
"I haven't seen it either; no worries, we're not planning on summoning it anyway."
